The rover is positioned on the right side of the image, showing its intricate metallic body, six treaded wheels, and tall camera mast, which is turned to "look" directly at the viewer. The rocky, textured ground slopes downward to the left, revealing a vast, desolate basin and distant crater rims under a dusty, pale grayish-tan sky.

NASA’s Perseverance Mars rover has uncovered evidence that a 245-foot-thick (75-meter-thick) stack of ancient rock on the rim of Jezero Crater was built by repeated asteroid impacts. Referred to as the “Broom Point member” by the rover’s science team, this sequence of layered bedrock is likely more than 3.9 billion years old, making it among … Continue reading NASA’s Perseverance Rover Reads Record of Ancient Mars Impacts
